From Pathfinder Wiki
Baleen makes up baleen plates, which are arranged in two parallel rows that look like combs of thick hair; they are attached to the upper jaws of baleen whales. Whales use these combs for filter feeding. Baleen whales scoop vast amounts of water into their mouths, and then push the water back out their mouths through the baleen plates. The baleen plates prevent fish and plankton from flowing out of their mouths. Whales are the only vertebrate group to use this method of feeding in great abundance (flamingos and crabeater seals use similar methods, but do not have baleen), and it has allowed them to grow to immense sizes.
